yes it can work up to a point. Change the word from "performance" to "collaborative" and it's going to work on dispelling the gatekeeper rape myth that "women don't enjoy sex anyway so how's a guy to know whether he's raping or not."
BUt it's only going to work up to a point, because as dittany says, the concept of a man having to notice that a woman enjoys sex will actually blur the lines between rape and sex, when the two are very different things. It makes me uneasy in many ways to talk about a "woman's enjoyment of sex" in the context of rape, because, yes, rape is about power, control and an evil bastard. It doesn't happen by accident.
Still...I do think that it's worth a try, it certainly won't do any harm to get the idea out that a woman knows whether she's enjoying being penetrated or not. Right now, it seems to me that the courts can't accept that. They think, "women are gatekeepers and aren't much keen on sex anyway, so what difference does it make to them whether the man meant to rape her or not". I think the "collaborative" concept will get rid of that myth, and that will be really good.
